This failure has only been seen when attempting to flash reprogram a newly installed ECM service replacement part.

This flash failure is intermittent and does not affect all Cummins-equipped vehicles when flashing a newly installed ECM service replacement part.

SUGGESTION:

When flash reprogramming this ECU, it is recommended that you DO NOT USE a wireless networking connection.

The safest networking environment using the wiTECH Diagnostic Application is to connect your PC (running the wiTECH Diagnostic Application) and either the wiPOD VCI or StarMOBILE device directly to the wiTECH Access Gateway using an Ethernet connection

Battery charge level must be adequate; do not attempt to flash reprogram the ECM without a battery charger installed.
